Tbh, little, mostly convenience (best metaphor I can give is installing Sublime Text vs manually installing your vim and your own personal configs). By default it supports a bunch of interesting things, autocomplete, iteractive filesystem navigation, theming (I used oh-my-fish in the past, not sure how it is now), etc. I like it, I would love to run it as my main shell, but I just do too much scripting for my own good to hop on this wagon.
